673196 divided by 21 
Let's see how many times 21 fits into 673196.

Going ahead to step 1:
The number 21 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 21

Advancing to step 2:
If we divide 67 by 21, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 63 from 67 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 21

Going ahead to step 3:
21 goes into 43 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 42 from 43 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 21

Moving on to step 4:
11 divided by 21 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 320.0
If we take 0 away from 11, we end up with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 21

Going ahead to step 5:
21 can be fit into 119 5 times, resulting in a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 3205.0
Subtracting 105 from 119 leaves us with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 21

Advancing to step 6:
The number 21 fits into 146 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 32056.0
If we take 126 away from 146, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 32056.9
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 32056.95
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 32056.952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 32056.9523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 32056.95238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 32056.95238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 32056.9523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 32056.95238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 32056.95238095 with a remaining 5e-09.
